LOUIS n. r. WAGHTER, or NEW YORK, N. Y.

WATCHCASE.

Application filed April 9, 1917.

To all whom it may concern:

Be it known that I, LOUIS E. F. l/VACH- 'rnn, residing in the city and county of New York, State of New York, have invented certain new and useful Improvements in Vatchcases, of which the following is a specification, reference being had to the accompanying drawings, illustrative of one particular embodiment of my invention.

My invention relates to'cases and more particularly to the complete incasing of awatch movement with the winding and setting stem and its crown inclosed andfastened on and within the walls of a metal casing, and which directly incloses allot the parts and supports and protects same within its covers, still permitting observation of the dial and hands of the movement.

This is effected by making a metal casing with its interior of s'ufi'icient size and shape that itwill accommodate a watch movement and attached or connected with it its wind ing and setting mechanism with crown, all within its walls, and in conjunction with which I provide means whereby access is bad to the watch movement for winding and setting the movement by its crown.

Such a construction makes it possible to produce a water-tight casing to take a watch movement with its crown and winding and setting apparatus and protect the whole within its walls, and thereby excludes the necessity of av special casing necessary for ordinary watches to protect the crown and pendant against entrance of moisture or dust to the watch movement.

In the particular embodiment of my invention shown in the accompanying draw- 1ngs,

Figure 1 is a side elevation of a closed case,

Fig. 2 is'a side elevation, partly in section, of the article as shown in-Fig. 1, slightly modified in detail.

Fig. 2 is a detail spring support for the works within the case.

Fig. 3 is a side elevation of Fig. l, with the case open.

Fig. e is a side elevation in part section of a modified form of the pocket watch.

Fig. 5 is a front or face View of Fig. 4.

Fig. 6 is a vertical section of a case, on a larger scale. part broken away, indicating water-tight joint construction.

The case comprises the back section A and the front section B hinged at C, so that the Specification of Letters Patent.

edges a-b may be brought together to form a tight joint, with a clip D to hold them securely together.

- A clip E on the inside of the case cover A serves to engage the winding stem F of a watch works G, which works are connected to thehinge C by a suitable member H, the work s having the {ace J visible when the cover B is separated from the cover A and the works G lie against the inside of the cover A, held in position by. the clip E.

The joint H may be modified to embody the spring connection as shown in Fig. 2", by means of which it is supported in a resilient way to take up jar, and at the same time permits the hinging of the works with respect to the case.

In Figs. 4 and 5, the case A has the works G hinged to it at L. The complementary portion of the cover B is open at M, having reentrant edges or rim N, so arranged that they engage a crystal 0 covering the front of the works G, whereby when closed the opening M permits observation of the dialand reading the watch, and the edges engage the crystal so as to form the closure and complete the entire protection of the watch works, winding, setting and crown and all parts of the watch.

The link P may be attached at one portion of the case or a clip Q, may be attached to one portion on the outside of one of the case covers for convenience of securing to any suitable connection for wearing.

In Fig. 6, the case A has a circular lip R, which engages a groove S on the cover part B. thereby forming a tight or Waterproof joint. while the clip D serves to lock the two covers together. A knob T afiords a slight protuberance which maybe readily pressed to disconnect the latch securing the joint.

The works and the setting stem F projecting through the works dust-ring, as shown, and having the crown V adapted for winding and setting, are surrounded by the case, thus completing the watch,-with "all its mechanism completely inclosed, as shown in Figs. 2 and 4, within the case covers when closed.

It will thus be seen that the entire mechanism of the watch which does not require attention for purposes of observation, is inclosed: likewise all of the mechanism that should be protected from the elements and wear, or accident of any kind, are com1 'pletely inclosed within the case, at the same a watch movement assembled with its winding and setting stem and crown within the walls of the case, without the necessity of having a supplementary case for protection of the crown and pendant.

Various modifications may be made in detail and dimensions without departing from the spiritof my invention, but what I claim and desire to secure by Letters Patent is:

l. A watch case having its interior constructed and shaped to inclose and support a watch movement assembled with its winding and setting stem and crown, all within the walls. ofsaid case and having a sight aperture 6n one side to permit the reading of the dial.

2. A watch comprising a stem winding and setting watch movement, a supporting case therefor completely inclosing said movement with its stem winding and setting devices, a

sight area on one side of said case and means to secure themovement to the interior of said case in predetermined relation to said sight area.

3. A watch case without exterior projections for supporting the winding and setting mechanism and crown, and having means on the interior for supporting a stem winding and setting watch movement with its crown, and having a sight aperture on one side overlying the face side of the movement.

4. A watch case adapted for complete inclosure of a stem-winding and setting movement, and closely confining the same with a circular periphery substantially coextensive with one side of said works and extending eccentrically about said works to closely confine the stem, an eccentric sight area located in one side of said case and registering circularly with a. dial on said movement.

Signed at New York, this 7th day of April, 1917.
